Fibrillin-1 is a protein that plays a crucial role in the structure and function of connective tissues in the body. It is a member of the fibrillin family, which also includes fibrillin-2 and fibrillin-3. Fibrillin-1 is primarily found in elastic fibers, which are essential components of connective tissues such as skin, blood vessels, and lung tissue. These fibers provide elasticity and resilience, allowing tissues to stretch and return to their original shape.

The primary function of fibrillin-1 is to stabilize the elastic fibers within the extracellular matrix. It does this by forming a complex with other proteins, including fibulin-5 and elastin. This complex helps to organize and maintain the structure of the elastic fibers, ensuring their proper function. Fibrillin-1 also plays a role in cell signaling and tissue repair, contributing to the overall health and integrity of connective tissues.

Mutations in the FBN1 gene, which encodes fibrillin-1, can lead to a group of genetic disorders known as Marfan syndrome and related disorders. These conditions are characterized by abnormalities in connective tissue, including tall stature, long limbs, and cardiovascular issues. The severity of symptoms can vary widely among affected individuals, depending on the specific mutation and its effect on the structure and function of fibrillin-1.

Research into fibrillin-1 and its role in connective tissue health continues to be an active area of study. Understanding the molecular mechanisms underlying its function and the effects of mutations can provide valuable insights into the development of new therapies for connective tissue disorders.
